Chatifield, Chicago, Ill., assigner to Foi-mold Plastics, Inc., Blue Island, Iii., a corporation of Iliinois Filed May 9, 1966. Ser. No. 548,534 5 Claims. (Cl. 222-485) ABSTRACT F THE DISCLOSURE A dispensing closure of the type in which an apertured cap is rotatably mounted to a neck having 'an offset wall portion selectively alignable with the cap aperture for dispensing, wherein the neck is provided with a circumferential groove and a latch recess is disposed axially inwardly of the groove and intersecting the wall of the groove radially inwardly of the innermost surface of a latch lug mounted on the cap for facility in assembling the cap and neck, the circumferential groove receiving a retaining ring protruding from an inner surface of the cap. When venting of the closure is desired, appropriate aperture means are provided in the cap and in the neck arcuately differentially spaced from the dispensing aperture.

This invention relates generally to a closure assembly and more particularly to a dispensing cap assembly for a flexible tube or other container.

Many paste products, such as toothpaste and shaving cream, are commonly marketed in liexible tubes. The tubes are usually closed by a separate cap which is screwed onto a threaded neck of the tube. When the contents of the tube are to be used, the cap is unscrewed from the neck of the tube. The contents of the flexible tube, rsuch as toothpaste or shaving cream, may then be dispensed from the neck of the tube. After the desired amount of the paste product has been dispensed, the cap must be screwed back onto the tube.

The conventional, separate cap provides a satisfactory closure for a container if the cap is placed back on the tube after use. However, if the cap is lost or accidentally left off, some of the paste in the tube or other container will usually be smeared on the surroundings. After a cap has been off the tube for a period of time, the paste in the neck portion of the tube will harden and clog the tube.

Therefore, one of the objects of this invention is to provide a cap assembly for a container wherein the container is always readily covered after usage.

Another object of this invention is to provide a cap assembly which cannot become separated from the container with which it is associated.

These and other objects and features of the invention will become more apparent from a reading of the following detailed description taken in connection with the accompanying drawings, wherein:

FIG. 12 is a sectional view of a third embodiment of my invention wherein the closure cap assembly is utilized with a container which is integrally formed with a neck portion of the cap assembly.

Referring now to the drawings in greater detail, there is shown in FIG. 1 a first embodiment of my invention. This first embodiment includes a iiexible tube 10 having an upper end portion to which the cap assembly 12 is connected. The cap assembly 12 includes a cap or cover 14 which is telescopically mounted on a neck or connector 16. The cap 14 has an arcuate, oblong dispensing aperture 18 located in yan upper end wall 20.

From an inspection of FIG. 3 it will be seen that, when the cap 14 is located in a lirst, open or dispensing position, the aperture 18 will be unobstructed and a paste or other substance 21 can be dispensed from the tube 10 through the aperture 18. The paste 21 is dispensed by squeezing the tube and forcing the paste to flow through a central passage 22 in the neck 16 and out the aperture 18 in the cap. The cap 14 is fastened to the neck 16 by an inwardly protruding, retaining ring 24 which is formed on an inner surface 25 of the cap. 'I'he ring 24 is circular in shape and extends completely around the cap 14 and slidably mates with a circumferential groove 26 in the neck 16. The groove 26 permits the cap to be rotated rrelative to the neck 16 while preventing it from becoming separated from the neck.

A radially outwardly offset, lower skirt or ange 27 is connected to the retaining ring 24 by an oblique sidewall 28. The upper end wall 20 of the cap is joined to the retaining ring 24 by a cylindrical sidewall 30. The sidewall 3i) and skirt 27 have a series of vertical utes or knurls 32 in their outer surfaces to facilitate gripping of the cap 14.

Referring now to FIGS. 2 and 3, a stop lug 34 extends downwardly from the retaining ring 24. Stop lug 34 is connected to the retaining ring and has an inner surface 35 which is vertically aligned with the inner surface Z5 of the wall 30. Thus, the retaining ring 24 extends inwardly of the stop lug 34 so that the retaining ring 24 securely engages the neck portion of the cap assembly.

From an inspection of FIG. 2, it will be seen that the neck 16 of the cap assembly includes a generally cylindrical upper wall portion 38 which is connected toa lower wall or base portion 40 of generally frustoconical shape. The lower wall or base portion 40 is connected to the upper wall portion 38 by the circumferential groove or recess 26. The cap 14 and neck 16 are both made of a suitable polymeric material and have a slight spring or resiliency. This resiliency permits the cap and retaining ring 24 to be forced downwardly in a telescopic relationr ship with the upper sidewall 38 of the neck 16. The retaining ring 24 will then snap into position in the groove 26. The sliding of the cap 14 downwardly, so that the retaining ring 24 enters the groove 26, is facilitated by the inwardly sloping sidewall 28 of the cap. The sidewall 28 tends to center the cap 14 automatically .on the neck 16 when the cap is being forced downwardly relative to the neck. The cap 14 will then be retained in a coaxial telescopic relationship with the neck 16 by the mating ring 24 and groove 26.

The upper Iwall 38 of the neck 16 includes an upwardly extending blocking wall 44. An upper surface 45 of the blocking wall 44 engages the inner surface of the end wall 20 of the cap. As is best seen in FIGS. 4 and 7, the upper surface 45 of the blocking wall is located at the same radial distance from the center of the neck 16 as is the aperture 18 of the cap 14 which is coaxially mounted with the neck 16. When the cap 14 is rotated to the closed position, the aperture 18 is sealed or closed by the outer surface 45 of the blocking wall 44. By rotating the cap to the dispensing position, as shown in FIG. 3, the aperture 18 will be moved away from the blocking wall 14 and adjacent to a dispensing area 46 of the upper wall 38. When the aperture 18 is adjacent to the dispensing area 46, the contents of the tube 10 may be forced upwardly through passage 22 in the neck 16 and out through the aperture 18. However, the tubular passage `22 will be blocked, by the transverse end wall 20, when the aperture 18 is rotated to the closed position 'shown in FIG. 4.

Referring now to FIG. 4 taken in conjunction with FIGS. and 6, the cap 14 is retained in the closed position by a latch structure 50 which engages the stop lug 34 on the inner surface of the cap 1'4 to hold the cap 14 in the closed position. The latch structure v50 is mounted in an arcuate latch recess 52 that is forrned in the lower sidewall 40 of the neck 16. The recess 52 is defined by a pair of vertical end walls 54 and 56 which are interconnected by an arcuate sidewall 60 an'd base wall 62. As is shown in FIG. 3, the sidewall 60 of lthe latch recess 52 intersects a lower rwall portion of the groove 26 and is in substantially vertical alignment with the outer surface of the upper wall 38. When the cap 14 is snapped onto the neck 16, the innermost surface of the latch lug 34 clears the wall 60 of the latch recess 52. In order to couple the cap and neck portions of the cap assembly, the latch lug 34 is vertically aligned with a portion of the latch recess 52. If the latch lug 34 is not so aligned, the downwardly sloping wall 40 of the base of the neck 16 will engage the lug 34 and prevent the cap from being telescoped completely onto the neck.

The latch assembly 50 includes a second latch lug 64 which is positioned adjacent to the end wall 54 and protrudes outwardly from the sidewall 60 into the latch recess 52. The innermost portion of the -latch lug 34 protrudes into the recess 52 far enough to engage or abut the second latch lug 64. Thus, when the rst latch lug 34 is positioned adjacent the end wall 54, as shown in FIG. 6, the second latch lug 64 will retain the -first latch lug 34 and cap 14 in the closed position. Since the two latch lugs are made of a resilient plastic having a low coefiicient of friction, the lirst latch lug 34 may be forced past 'the outermost portion of the second latch lug 64 to rotate the cap to the open position shown in FIG. 5.

A sealing bead or ring 70 is connected to the upper wall 38 intermediate the outer end of the neck and the groove or recess 26. The sealing bead 70 engages an inner surface of the wall 30 of the cap to seal the dispensing area 46 from the groove and latch assembly 50. The bead 70 prevents the flow of paste from the dispensing area 46 downwardly into the retaining ring and latch recess. Thus, the gap 72 between the wall 30 of the cap and the surface of the upper wall 38 is blocked by the bead 70.

As is best seen in FIG. 3, the neck 16 is connected to the flexible tube by means of a connecting flange or rim 78. The flange or rim 78 is formed integrally with and radiates outwardly from the lower base wall 40 of the neck 16. The exible tube 10 is connected to the ange or rim 78 by means of an annular collar 80 which is composed yof a suitable, malleable alloy for mounting the flexible tube 10. The collar 80 includes upper and lower mounting flanges 82 and 84 which engage the upper and lower surfaces of the flange or rim 78. The construction of the collar is well known to those skilled in the art and does not, per se, constitute a part of this invention.

For purposes of affording a more complete understanding of the invention, it is advantageous now to provide a functional description of the mode of operation of the embodiment of my invention shown in FIGS. 1 to 7. The cap assembly 12 includes a cap 14 and a neck member 16 which is connected to a flexible tube 10 by means of a collar 80. The cap 14 has a dispensing aperture 18 in the outer end wall 20 through which the contents of the flexible tube 10 are dispensed. When the cap is in the open position shown in FIG. 3, the contents of the tube 10 can be forced outwardly through the passage 22 to the dispensing area 46, and out the aperture 18. By rotating the cap 14, relative to the neck 16, the dispensing aperture 18 is sealed by the upper surface 45 of the blocking wall 44. When the cap is so positioned, the contents of the tube 10 cannot be forced out of the aperture 18, since the blocking wall 44 closes the aperture against fluid communication with the dispensing area 46. If a reduced or partial flow of the contents of the tube 10 is desired, the cap V14 may be rotated so that the aperture 18 is only partially blocked by the blocking wall 44. When the arcuate aperture 18 is only partially blocked, the flow of the contents of the flexible tube 10 will be restricted but not completely blocked. Since the retaining ring 24 matingly 'couples the cap 14 with the neck 16, the cap 14 cannot be inadvertently mislaid or lost.

The cap 14 may be latched in the closed position by a first latch lug 34 on the interior of the cap 14 which engages a second latch lug 64 on the neck 16. The latching lug 64 will engage the innermost portion of the latching lug 34 to retain the cap 14 in the closed position (see FIGS. 4 and 6). When a rotative or turning force is applied to the cap 14, the latching lug 34 will deformably slide past the outer surface of the latching lug 64. The cap 14 may then be easily adjusted so that the aperture 18 is in any desired position relative to the blocking wall 44. While only one latching lug 64 has been shown attached to the neck 16, it will be apparent to those skilled in the art that several latching lugs could be attached to the neck 14, in spaced apart locations in the latching recess S0, to engage the cap latching lug 34 to retain the cap 14 in any one of several predetermined locations. Thus, a lug could be positioned in the latching recess 50 so that the aperture 18 would be only half closed (see FIG. 7) by the blocking wall 44.

A second embodiment of my invention is shown in FIG. 8 wherein a closure cap assembly 100, similar to the cap assembly 1-2 of FIGS. l to 7, is adapted for permanent installation on a glass container 102. The closure assembly includes a cap 104, of a suitable polymeric material, which is rotatably mounted on a neck 106 which is positioned in a telescopic relationship with the interior of the cap 10'4. The neck 106, also formed from a polymeric material, is securely mounted on the container 102 by means of radially outwardly extending shoulders 108. The shoulders 108 engage an annular radially inwardly extending shoulder or ange 110 formed at a mouth or upper end portion 112 of the container 102. The neck member 106 is mounted in the container 102 by pressing a rounded lower end 114 of the neck 106 into the mouth 112 of the container 102. An annular radially outwardly projecting protuberance 116 engages an annular arcuate recess 118 at the mouth of the bottle to position the neck member 106- vertically relative to the mouth 112 of the container 102. The radially outwardly extending protuberance 116 also positions the neck mem-ber to prevent it from being inserted completely into the container 102 during an assembly operation.

The neck member 106 includes a longitudinally extending generally cylindrical passage 120 which is posi- 75 tioned ciaxially with the longitudinal axis of the container 102. The passage 120 extends from the lower end 114 of the neck member to the uppermost end of the neck member where the passage is restricted by a blocking wall 122. The blocking wall 122 restrictsthe passage 120 to form an arcuate dispensing aperture or area 124 which is defined by a blocking wall portion 126 of the neck member 106 and an arcuate vertically extending surface 128 of the blocking wall 122. The passage 120 also extends through a second arcuate dispensing aperture 130 which is formed in the top panel or surface of the cap 104. From an inspection of FIG. 9 it is apparent that, while the dispensing area or aperture 124 in the neck member is slightly larger than the dispensing aperture 130 in the cap member, the two apertures are positioned the same radial distance outwardly from the center of the cap. It is also apparent that the two arcuate apertures 124 and 130 are geometrically similar in shape, that is they have the same shape and d iier only in size and position.

The cap member 104 is rotatably fastened to the neck 106 by an inwardly protruding annular retaining ring 132 which is formed in an inner surface of the cap 104. The retaining ring 132 is positioned in sliding mating engagement with an arcuate annular recess 134 in the neck 106. The cap :member is further secured to the neck member by means of an annular sealing bead 135 which is formed in the neck and is in sliding mating engagement with an arcuate recess 138 in the cap member 104. The bead 136, in addition to retaining the cap 104 on the neck 106, seals the joint between the cap and the neck 105 to prevent the contents of the container 102 from leaking out between the cap and neck.

The closure assembly 100 further includes a vent aperture structure 140 which permits air to enter the container 102, through the cap 104, as fluid is dispensed through the apertures 124 and 130. The vent structure 140 includes a lirst arcuate vent aperture 142 which extends through the blocking Wall 122 and a second arcuate vent aperture 144 which extends through the upper panel 146 of the cap. From a comparison of FIGS. 8 and 9 it will be apparent that the two arcuate apertures 142 and 144 are positioned the same radial distance outwardly from the center of the cap 104. The apertures 142 and 144 are congruent, that is they have the same size and coniguration. Thus, only the aperture 144 is indicated in FIG. 9, since the aperture 142 is in direct vertical alignment with the aperture 144. It `should also be noted that the dispensing apertures 12.4 and 130 are positioned radially outwardly of the Vent apertures 142 and 144, and that the vent apertures and dispensing apertures are all geometrically similar in shape to each other.

The closure assembly is shown in the open or dispensing position of FIGS. 8 and 9 in the closed or sealed position in FIGS. y and l1. The cap 104 is rotated from the open position of FIG. 8 to the closed position of FIG. 10 by grasping the outer surface of the cap, which is suitably knurled, and twisting the cap relative to the container 102. When the cap is twisted to the closed position shown in FIG. 10, the dispensing aperture 130 and the vent aperture 144 in an upper panel or surface 146 of the cap are blocked or sealed by an upper surface 150 of the blocking wall 122 which is positioned in an abutting sliding engagement with a lower inner surface 152 of the cap 104. Similarly, the inner surface 152 blocks or seals the dispensing aperture or area 124 in the neck 106 and the vent aperture 142 in the blocking wall 122.

As will be apparent from an inspection of FIG. 1l, it is the radially outward location of the dispensing apertures 124 and 132, relative to the vent apertures 144 and 142, which enables the blocking wall 122 and upper panel or surface 148 of the cap to seal the dispensing and vent apertures when the lcap is turned to the closed position, If the vent and dispensing apertures were located at the same radial distance from the center of the cap, the apertures would only be partially sealed when the 6 cap is turned to the closed position. It is apparent that, if the apertures were only partially sealed when the cap is in the closed position, the contents of the container would be spilled out.

The cap member 104 also includes a depending cylindrical skirt portion 156 shown in FIGS. 8 and 10. The skirt 156 has an annular radially inwardly extending shoulder 158 to integrally connect the skirt 155 to the upper dispensing portion of the cap. An inner surface 160 of the shoulder slidingly engages an upper surface 162 .of the mouth 112 of the container. An inner surface 163 of the skirt 156 includes a plurality of annular inwardly extending wedge shaped locking tangs or ridges 164. These inwardly extending tangs or ridges grippingly engage a plurality of annular recesses 166 which are formed in the container 102. The locking tangs 164 have flat substantially horizontal locking surfaces 168 which are positioned in sliding engagement with flat substantially horizontal locking surfaces 170 in the container 102. The locking surfaces 168 and 170 prevent the cap from being removed from the container 102. The locking tangs have annular axially sloping side surfaces 172 which permit the cap to be moved downwardly past the wedge shaped recesses 106 when the cap is positioned on the container during assembly.

A third embodiment of my invention is shown in FIG. l2. This embodiment is similar to the embodiment shown in FIGS. 8 to l1, and like numerals have been used to designate like parts with the suix a being employed to distinguish the elements from those shown in FIGS. S to 11. The closure assembly a includes a cap which is made of a suitable polymeric material and is rotatably mounted on a neck 10611 which is integrally formed with a polymeric container 102a. The cap 1046: includes an arcuate dispensing aperture e which, in the open position shown in FIG. 12, is aligned with an arcuate dispensing aperture 1240 which is formed in the neck portion 106a of the container 102a. rThe cap 104:1 also includes an arcuate vent aperture 144:1 which, when the cap is in the open position, is aligned with an arcuate vent aperture 142a in the blocking wall 122e of the neck 106a. The cap 104a is rotatably retained on the neck 106e by an inwardly protruding annular retaining ring 132:1. Also, an outwardly protruding sealing bead 136e is formed in the neck portion 106e of the container 102:1. In addition to the retaining ring 132g and sealing bead 136a, which cooperate with 'the neck and cap in the manner previously described for the embodiment of FIGS. 8 and 11, an annular retaining shoulder 200 is also provided. The retaining shoulder protrudes radially outwardly from the neck portion 10611 of the container 102er. The retaining shoulder 200 engages a corresponding mating recess 202 in the cap 104e. The mating shoulder and recess prevent the cap from being disengaged from the neck portion 106a of the container 102e. From a com.- parison of the embodiments of FIGS. 8 to ll with yFIG. l2, it will be apparent that the embodiment of FIG. l2 is similar to the embodiments of FIGS. 8 to 11, with the exception that the neck 106a is integrally formed with the container 102a.

In order to describe the embodiments of FIGS. 8 through 12 more fully, the following functional description is given of the mode in which the component parts cooperate. The closure assembly 100 includes a cap 104 which is rotatable from a first open position wherein an arcuate dispensing aperture 130 in the upper wall or panel of the cap 104 is positioned in vertical alignment with an arcuate dispensing aperture or area 124 which is formed in the blocking wall 122. When lluid is poured from the container 102 through the passage 120 and the dispensing apertures 124 and 130, air will enter the aligned arcuate vent apertures 142 and 144 to provide a relatively smooth rate of flow of the iiuid from the container 102. When the dispensing apertures 124 and 130 are aligned vertically, as shown in FIG. 9, the vent apertures 142 and 144 are also aligned vertcially. If the cap is partially closed, so that the dispensing apertures are partially blocked by the blocking wall 122 and the panel 146 of the cap 104, the vent apertures 142 and 144 will also be partially blocked. This partial blocking of the dispensing apertures and vent apertures will reduce the rate of fiow of fluid from the passage 122 and the dispensing apertures 124 and 130.

When the cap is further rotated to the closed position, shown in FIGS. and 11, the dispensing aperture 130 and vent 144 in the cap are sealed by the blocking wall 122. The dispensing aperture 124 and vent aperture 142 in the neck 106 will be sealed by the upper panel 146 of the cap 104. Since the neck 106 and cap 104 are both made of a polymeric material, there will be a tight sealing engagement between the blocking wall 122 and the upper panel 146 of the cap 104. It will be apparent, from an inspection of FIG. 12, that the embodiment disclosed therein will operate in substantially the same manner.

Referring now specifically to the embodiment disclosed in FIGS. 8 to l1, the cap 104 and neck 106 are retained in position on the upper end of the container 102 by the radially outwardly extending shoulder 108 of the neck and the radially inwardly projecting locking tangs 164 on the interior surface of the skirt 156 of the cap 104. When the cap is rotated, the locking tangs 164 will slide in the mating recesses 166 in the glass container 102. An attempt to remove the cap from the container 102 will result in the wedge shaped locking tangs 164 gripping the upper surface of the recess 166 to prevent relative movement between the container 102 and the cap 104. At the same time, the shoulders 108 will engage the inwardly projecting iiange 110 which is formed in the mouth of the container 102. Thus, it will be apparent that the closure assembly 100 cannot, Without great difficulty, be removed from the end of the container 102. Since the closure asembly 100 cannot be removed from the end of the container, it is apparent that the container cannot be easily refilled. This feature is extremely advantageous for use in conjunction with containers which the law prohibits from being refilled.

The embodiment of FIG. 12 is similar to that of FIGS. 8 to l1 with the exception that the neck portion 106:1 is integrally formed with the main body of the container 102a. In the embodiment of FIG. 12 a lower retaining shoulder 200 is provided to prevent the cap 104:1 from being removed from the neck portion 106:1 of the container 10211. The cooperation between the vent apertures, dispensing apertures, blocking wall and upper panel of the cap is substantially the same as that for the embodiments of FIGS. 8 to 11, and will be apparent, in View of the foregoing remarks.
